.I don't use the phone that much but the text read back is a handy thing!
yeah i like that feature, but i also have twitter updates to my phone and it can get a bit annoying on a long drive
regarding the 620, wouldn't you need the sim in it for nokia drive to work? just a thought? alternatively, does it have a mass storage mode via usb? failing that maybe just use a 64gb usb stick or adapter for the memory card you already have and whack it in the usb slot?
